mRovnMnN'r IN WELL-TUBES.

The Schedule referred to these Letters Patent and making part af the same.

To all whom 'it may concern:

Be it known that I, DELoss A DANFORTH, of Elkhart, in the county1 of Elkhart, and State of Indiana, have invented ainewand useful Improvement in Drive- Well-Tubes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, referencebeing hadl to the accompanying drawings, making a part oi' this specication, in which- Figure l is a side View of tube and point, with outer punctured case;

, Figure 2 is a 'vertical section of the same; and

Figure 3, an enlarged view of' the punctures.

Like letters in the different figures of thedrawingsl indicate like parts. a

My invention consists, rst, ofthe construction of an outer case over a drive-Well-tube, punctured so as to admit water, but notsand; second, of a plug securely fastened in the tube, a proper distance from the lower end thereof, for the upper part of the point to b'ear against, to prevent the shoulders of, the same from being cut or split o` by the end of the tube, -in driving it into the ground.

. A represents the outer case, and c e c, the'punctures therein, which are made with a punch, the end of which is provided with four or more cutters, tapering tof-a point toward thecentre of the punch, but not meeting, so that the punctures do not join in the centre, as shown in iig 3.

Alternate rows of the punctures are made by placing the punch or stamp, forming them, on the outside ofthe plate of the Vouter case, producing inwardly-projecting edges, which rest against the tube, holding the' walls of the case from the tube, and thus allowing space for the passage of the Water totheapertures in the tube. 4

The case is stronger, and operates better, by not joining the punctures in the centre, for, if joined, the.

point in the angles between them would be liable to be bent or sprung apart', which would produce an opening large enough to admit sand.

B is -a metallic stop or plug, securely fastened by rivet, or otherwise, in the tube C, a proper distance from the end of the same, for the upper end of point D to bear against, as shown in fig. 2. r

The shoulders of point D are inwardly depressed, as shown at l d in fig. 2, and the lower edge of the tube is made to fit therein, for the purpose of avoiding the spreading of the tube in driving the point into the ground.

The outer case, with punctures as described, will l admitwater, but prevent sand In localities where the ground is free Vfrom rocks or other hard substances, Wooden 'instead of metallic points may be used, but ais-heretofore constructed,the

shoulders were liable to be cut or split of by the pressure ofthe end of the tube in driving itin the ground.

This is 'prevented by the plug B bearing on the end of the tube, as described.

Having thus fully described my invention,

What I claim therein as new, and desire to secure by Letters Patent, is-'- l. The case A with punctures o o c, as constructed, alternately from the outside and inside of the case, so as to form alternate edgesand depressions on the outside and inside of the same, substantially as described.

2. Gase A, as constructed, and tube O, with -lug or stop B, in combination with the inwardly-depressed shoulders l l of the point D,substantially as described.

As evidence that I claim the foregoing, Ihave hereunto set my hand, in the presence of two witnesses.
